When the credits roll, they'll hear "All I've Ever Needed," a duet recorded by Huntsville's Paul McDonald and his wife, actress Nikki Reed. She portrays a vampire named Rosalie in all of the "Twilight" films.

The couple met in 2011 when singer-songwriter McDonald, 28, was a contestant on the 10th season of "American Idol." That year, the finalists went to premiere of the movie "Red Riding Hood," also attended by Reed.

Love at first sight? All we know is that Reed, 24, and McDonald were engaged within a few months. They married in October 2011.

McDonald, an Alabama native, performed on the Southeastern nightclub circuit with the band Hightide Blues and later fronted the Grand Magnolias. He gained national attention on 'Idol," and has been dabbling in acting this year, with a guest spot on NBC's "Parenthood."

McDonald and Reed's tune also appears on the soundtrack record for "The Twilight Saga: Breaking Dawn -- Part 2."

Here's the full track listing for the album, released Nov.13 on Chop Shop/Atlantic:
